Re: Advice for someone new?
What odudog said...
Aikido is something that takes time to develop. It's definitely not an instant gratifaction type of an art. When you learn striking arts you see the immediate results. Aikido is such a different animal. It may take a little while to understand the basic movements. Developing your ukemi is very important. Forward and backward rolls, breakfalls, and being martially aware is something that will come with practice.
I wish I would've discovered Aikido at your age. You're half the age I was when I started, but I just glad that I found something that gives me so much in return.
Have fun and good luck.
